^i wouldn't even say this is showroom dummies, rather the melody becomes the melody for showroom dummies 2 years later, but this instrumental is definitely something else (mitternacht comes in at the end)...the UK 1975 live bootleg as a whole is great if you like the early kraftwerk albums.

another live early kraftwerk track given a ridiculous name on a bootleg

this is another crazy unkraftwerkian live bootleg, either goes by K4 or Bremen Radio 1971.
